To all whom it m (12 concern:

Be it known that we, EDGAR VINCENT CHAMBERS and THoMAs CHARLES HAMMOND, subjects of King George V of Great Britain, residing at Huddersfield, in the county of York, England, have invented certain new and useful Improvements in Apparatus for Separating and Recovering Fibers and the like from Liquids, of which the following is a specification.

Our invention relates to filtering or straining apparatus of the type inwhich a revolving reticulated cylinder or disk is employed to separate solids from liquids, as

in the treatment of sewage or other liquid,

and comprises an improved construction and arrangement of apparatus for recovering wool or other fibers from liquids by means of which all fibers and the like are'removed from the liquid and the wool or other fibers collected or recovered separately from any dirt, sand, seeds, or other foreign matter.

According to the arrangement of the apparatus in carrying out our invention, the liquid is caused to flow through one or more perforated or reticulated screens revolving in a plane at right angles or substantially at right angles to the direction of the flow of the liquid and the essential feature of our invention is that with the screen or with each screen there cooperates a fixed upstanding board or surface arranged in proximity to the surface of the screen. The fibers which adhere to or become entangled in and carried up by the screen as it rotates are carried up between the fixed board or surface and the screen, and the movement of the latter with respect to the fixed surface causes the fibers to become more or less matted together or felted and at the same time squeezed so that they are delivered in a relatively dry state and in a suitable condition for handling.

We shall herein describe our improvements as arranged and adapted to deal with the liquor or effluent from wool washing or like machines. 7

In the accompanying drawings :Figure 1 is a plan view of the embodiment referred to; Fig. 2 is a cross section on the line A-A, Fig. 1, looking in the direction of the arrows, and Fig. 3 is a longitudinal section of the apparatus taken on the line B-B, Fig. 1.

Referring to the drawings, we employ, in the embodiment to be described, a suitable tank or vessel 64 havingan inlet chamber 1) and an outlet chamber 0. A drain pipe (Z communicates with the inlet chamber and a drain pipe awith the outlet chamber. A

pipe f connecting the inlet and outlet cha nbers enables the liquidor effluent, when so desired, to be run straight off through the, pipes d, f and 6 without being passed through the tank or vessel a, by closing the gates or valves g, h in the inlet and outlet chambers respectively. By opening the gates or valves g, h and closing a-gate or valve i controlling the entrance .to the pipe f,the

liquid or effluent is caused to pass throughthe tank or vessel a on its way to the drain pipe 6. Supported in bearings j, j above the 'tank or vessel a isa shaftk having secured thereon, in this instance two perforatedor reticulated circular screens Z. and m. The

screen Z is preferably of coarser or more which is of relatively fine mesh, is placedat the outlet end of the tank-or vessel, and a plate n closes the space below the screen so that the liquid or effluent is compelled as it passes out of the tank or vessel to the outlet chamber, to flow through the said screen we. The shaft 70 carrying thescreens Z and m is driven from any convenient source of motion to rotate the screens in the direction of the arrow C, Fig. 2. Arranged in proximity to that portion of the inlet surface of each screen which is moving upwardly, is an upstanding fixed board or surface 0 or 10, and at the upper end of Behind the screen Z shown, toward thepit so that heavy matters,

sinking to the bottom of the tank will gravitate into the pit. Brusl1es t0 and: v respectivelyengage the surfaces of the chamber '6 and flows through the interstices of the screen Z the longer fibers contained in the'liquid or eiiiuent being caught and re tamed by the screen. As the screen revolves,

the caught fibers are carried in behind the fixed boarder surface 0 and the rubbing action set up by the movement of the screen .with respect to the surface 0 causes the V fibers tobe'detached from the screen and to be rolledup and squeezed as the screen continues to revolve, until they reach the upper edge of'the surface 0 when they drop on to theplatform g. As the screen Z is of comparatively large mesh, the shorter fibers and any dirt or foreign bodies which may be present are.carried through the said screen intofthe'ta'nkorfvessel. The dirt and foreign bodies settle to the bottom of the tank =a'ndgrztvitate into the pit s from whence they are removed the elevator t'while the shorter fibers are carried forward bythe flow of the liquidor' efliuent to the screen m.

' Asitheiliquid or'elfluent flows through this screen, which. as before stated is of relatively fine' mesh, the whole, of the remaining fibers are caught andby the cojtiperation'of the-surface removed and delivered on to A "thep-latformni In cases-where no dirt or heavy foreign bodies are, present in the liquid or effluent, the' elevator. tmay be dispensed with. Where nosolids are presentin the liquidfor effluent,-

-one screen only with its respective upstandrng fixed board, may sufiice,but 1n most cases it is desirable to employ at least two screens as here-in shown, and any such larger number of screens may be employed as may, in anyiparticular case, be found desirable.

we claim as new and desire to The boards 0 and may be slightly inclined toward the screens if preferred;

' The improvements can be applied to existing machines in which fibers are treated and it is essential to remove such fibers from the liquid at the conclusion of the process.

Having thus described our invention, what secure by Letters Patent is 1. In a fiber separator, the combination, with a tank provided with an inlet and an outlet, of a separating disk of reticulated material journaled in the tank crosswise of the path of the liquid, and a stationary plane surface or board secured adjacent to that part of the front or inlet surface of the disk which moves upwardly in the tank.

2. In a fiber separator, the combination, with a tank provided with an inlet and an outlet, of a separating disk of reticulated material journaled in the tank crosswise of the path of the liquid, a stationary plane surface or board secured adjacent to that part of the front or inlet surface of the disk which moves upwardly in the tank, and a stationary brush which engages with that part of the front surface of the disk which moves downwardly in the tank.

3. In a fiber separator, the combination, with a tank provided with an inlet and an outlet, of a plurality of separating disks of "reticulated material journaled in the tank crosswise of the path of the liquid, said tank having also a receptacle for dirt arranged at its middle part between the said disks and below the level of its bottom, and stationary plane surfaces or boards secured adjacent to those parts of the front or inlet surfaces of the said disk which move upwardly in the tank.

In testimony whereof we aflix our signatures in the presence of two witnesses.
